Factors influencing engagement in in-person and remotely delivered lifestyle interventions for young adults with serious mental illness: A qualitative study

Aim: Young adults (ages 18–35) are underrepresented in lifestyle interventions for people with serious mental illness (SMI), such as schizophrenia, bipolar disorder, and severe depression, and little is known about factors influencing their engagement in these programmes. This qualitative study examined factors affecting engagement amongst young adults with SMI who were enrolled in a lifestyle intervention trial at community mental health centres. Methods: Seventeen young adults with SMI participated in this qualitative study. Participants were drawn from a 12-month randomized controlled trial (n = 150) comparing an in-person group lifestyle intervention augmented with mobile health technology (PeerFIT) to one-on-one personalized remote health coaching (BEAT) using purposive sampling. The 17 participants completed semi-structured qualitative interviews at post-intervention to explore their perceived benefits of the intervention and factors impacting engagement. We used a team-based descriptive qualitative approach to code transcripts and identify themes in the data. Results: Participants across both interventions reported experiencing improved ability to engage in health behaviour change. Participants described managing psychosocial stressors and family and other responsibilities that limited their ability to attend in-person PeerFIT sessions. The remote and flexible BEAT remote health coaching intervention appeared to facilitate engagement even in the context of challenging life circumstances. Conclusions: Remotely delivered lifestyle interventions can facilitate engagement amongst young adults with SMI navigating social stressors.
